Tuning the Si-N Interaction in Metalated Oligosilanylsilatranes.

ABSTRACT: Most known silatrane chemistry is concerned with examples where the attached silatrane substituent atom is that of an element more electronegative than silicon. The current study features silylated silatranes with a range of electropositive elements attached to the silyl group. The resulting compounds show different degrees of electron density on the silatrane-substituted silicon atom. This directly affects the Si-N interaction of the silatrane which can be monitored either by ²⁹Si NMR spectroscopy or directly by single crystal XRD analysis of the Si-N distance. Within the sample of study the Si-N distance is increased from 2.153 to 3.13 Å. Moreover, the bis(trimethylsilyl)silatranylsilyl unit was studied as a substituent for disilylated germylene adducts.
